It's bad, but it's not Post-Apocalypse bad. I'd still stay away from Asheville.
Yeah absolutely. If you don't have business in Asheville or the surrounding area, there's no reason to be there. Even if you live there, I recommend finding someplace to stay for a couple of weeks. It's still absolutely flooded with aid workers, guardsmen, charity volunteers, and search and rescue teams. Anyone there that doesn't absolutely need to be is just someone in the way or an extra mouth to feed.
No, it is on the government. 12-18 inches of rain and tropical storm winds were forecast 48 hours out. Where were emergency services preparing to distribute food and water and get the power back on?
There were literally teams staged for response 1-2 days before, even SAR teams. North Carolina put out EMAC requests for supplies and infrastructure assistance two days before the storm hit. The problem is 1. Nobody predicted this level of devastation 400-500 miles inland from landfall, 2. Retards didn't evacuate, despite the fact that a mandatory evacuation order was issued for some of these areas, and the government requisitioned school busses and Greyhounds to provide transport, and 3. It is hard as fuck to traverse the area up there. Even on good days it is difficult for heavy equipment to traverse fucking Appalachia, and now there's no roads and no power to a lot of these remote areas. Not to mention that, in some areas, the terrain itself has shifted. Where houses and neighborhoods used to be, there's thousands of tons of rock and mud that slid down a mountain.
law enforcement agency (town, county, or state) or the National Guard to legally block a road or arrest anyone.
This reminds me, I have something to report. I have seen some people posting stuff about unmarked federal law enforcement officers or dudes in tactical gear with no markings, of course speculation is what you'd expect. Anyways, I was curious and asked around, and these guys are Bureau of Prisons officers that have been deputized to assist with relief efforts. They are primarily there for site security at relief centers so there's not a repeat of the Superdome during Katrina. They should be able to provide credentials upon request. Some of them have badges but it's not universal, but they all will have law enforcement IDs.
This leads me into a other tangent, if you are being given orders and are not sure who they are or if they're legit, ask to see credentials. All agencies are required to provide them and the vast majority of the time it doesn't bother them at all. If someone refuses to provide credentials, they're a fraud, and if they are an asshole about it, report them immediately to the site commander, because that shit isn't tolerated.
